kv: Civil/Environmental Engineering \ ••• RFQ#12-04-02 Stan Edwards, P.E. Project Engineer City of Fort Lauderdale 200 North Andrews Avenue, Suite 200 r Fort Lauderdale, FL 33301 Phone: 954/828-5071 City of Fort Lauderdale uderdate Fax: 954/828-5074 Email: sedwards@fortlauderdale.gov Description of Services: At the request of The City of Fort Lauderdale, ECT conducted a subsurface investigation as a precursor to proposed new sewer line installation. The area of investigation was lim- ited to a linear corridor, a north-to-south utility easement on South Federal Highway. The easement be- gan at the southern property boundary of a former rental car facility and extended approximately 150 feet north. The corridor was located directly north of the intersection of SE 28`" Street and SE 4th Ave- nue in Fort Lauderdale. Historical documentation indicated that soil and groundwater contamination was found to be present at the former rental car facility. ECT conducted a search on the State of Florida OCULUS database which confirmed the presence of contamination at the site. The source of contamination was from a former UST located in the southwestern corner of the property. ECT also determined a second UST tank farm to be present located immediately north of the car wash. Given that historical documentation had indicated petroleum impacts located to the west of the utility corridor, the regional groundwater flow is generally southeast, and the preponderance of transmissive soils within the easement, there was some concern the easement could potentially have been impacted by petroleum related contaminants. In the absence of any data confirming the utility corridor to be free tof contaminants, ECT was contracted to conduct subsurface assessment within the utility easement. ECT supervised the advancement and sampling of eight soil borings, the installation and groundwater sampling of two shallow temporary monitoring wells, and groundwater sampling of an existing monitor- ing well. ' Based upon the results of the subsurface investigation, no petroleum impacts were identified in the soil or groundwater samples collected from within the utility easement, and the proposed City installation was able to proceed.
